The period of the old democratic revolution: The revolutionary contradiction of the Chinese people is the contradiction between the Republic of China and foreign capitalism and domestic feudalism.

During the period of the new-democratic revolution, the main contradiction in Chinese society was the contradiction between imperialism and the Chinese nation, and the contradiction between the masses of the people and feudalism and bureaucratic capitalism.

The new statement on the changes in the principal contradiction in Chinese society in the report of the 19th National Congress of the Communist Party of China is based on the new historical direction of China's development as socialism with Chinese characteristics enters a new era, and has sufficient practical basis.

The report pointed out: "China has stably solved the problem of food and clothing for more than one billion people, achieved moderate prosperity in general, and will soon build a moderately prosperous society in all respects. The people's needs for a better life are becoming increasingly broad, which not only puts forward higher requirements for material and cultural life, but also in democracy,

The requirements for the rule of law, fairness, justice, security, and environment are growing day by day. At the same time, China's social productivity level has improved significantly in general, and its social production capacity has entered the forefront of the world in many aspects. The more prominent problem is unbalanced and inadequate development.

It has become a major constraint in meeting the people’s growing needs for a better life.” This insightful discussion profoundly reflects the new changes in China’s social production and social needs.

The original statement about "the contradiction between the people's growing material and cultural needs and backward social production" can no longer accurately reflect this changed objective reality, and of course new generalizations are needed.
